Frequently Asked Questions
What is the maximum output current for the LP38690SD-3.3/NOPB?
The LP38690SD-3.3/NOPB supports a maximum output current of 150mA. It delivers this current with a typical dropout voltage of only 320mV at full load, making it suitable for battery-powered applications where input headroom is limited.
Which package does the LP38690SD-3.3/NOPB use and how many pins does it have?
The LP38690SD-3.3/NOPB comes in a SOT-23-5 package (5-pin small-outline transistor). This compact footprint makes it ideal for space-constrained PCB layouts in wearables, IoT sensors, and portable devices.
What input voltage range is supported by the LP38690SD-3.3/NOPB?
The LP38690SD-3.3/NOPB accepts input voltages from approximately 3.6V (output + dropout) up to 5.5V. It is commonly powered from a 5V USB rail or a single-cell Li-Ion battery through a boost converter.
Is the LP38690SD-3.3/NOPB RoHS compliant and lead-free?
Yes. The NOPB suffix explicitly indicates No Lead, No PBF (no lead-containing finish). The LP38690SD-3.3/NOPB is fully RoHS compliant and suitable for consumer and industrial applications with environmental compliance requirements.
What are good drop-in alternatives to the LP38690SD-3.3/NOPB?
Pin-compatible and functionally equivalent alternatives include the MIC5504-3.3YM5 (Microchip), XC6206P332MR (Torex), and AP2114HA-3.3TRG1 (Diodes Inc.). All are SOT-23-5 3.3V LDOs with similar current ratings and can serve as direct replacements in most designs.
